GENERAL DESCRIPTION
The AD5293 is a single-channel, 1024-position digital
The AD5293 performs the same electronic adjustment function as
a mechanical potentiometer with enhanced resolution, solid state
reliability, and superior low temperature coefficient performance.
This device is capable of operating at high voltages and supporting
both dual-supply operation at ±10.5 V to ±15 V and single-supply
operation at 21 V to 30 V.
The AD5293 offers guaranteed industry-leading low resistor
tolerance errors of ±1% with a nominal temperature coefficient
of 35 ppm/°C. The low resistor tolerance feature simplifies open-
loop applications as well as precision calibration and tolerance
matching applications.
The AD5293 is available in a compact 14-lead TSSOP package.
The part is guaranteed to operate over the extended industrial
temperature range of 40°C to +105°C.
1 In this data sheet, the terms digital potentiometer and RDAC are used
interchangeably.
